4BENJAMIN HAVILAND AND GEORGE PECK GUNN, OF HERKIMER, NEW' ""YORK, ASSIGNORS TO HENRY M. QUAOKENBUSH, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 290,230, dated December 18, 1883. Application filed October 25, 1883. (No model.)

To @ZZ whom, it may conceive;

Be 1t known that we, BENJAMIN HAvILAND and GEORGE PEcx GUNN, of the town of Herkimer, in the county of Herkimer, in the State of New York, have invented new and useful Improvements in Process of and Apparatus for Manufacturing Air-Gun Projectiles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The obj ect of this invention is to manufacture in a convenient, expeditious, inexpensive, and workmanlike manner air-gun projectiles of the class usually designated felted slugs and to that end the invention consists in the novel process hereinafter fully described, and specifically set forth in the claims.

To enable others skilled in the art to which the invention pertains to more readily comprehend and avail themselves of the invention, drawings are hereto annexed, illustrating an apparatus for carrying out the process, (see Figure 1,) and also showing a slug complete. (See Fig. 2.)

The apparatus employed consists, essentially, of a cylindrical vertical passage, @,through a suitable bed or table, A, in which passage moves a follower, b, formed at its upper end with a conical depression, which is the counterpart of the conical end to be formed on the lead slug, a support, B, being arranged under the table A to sustain the follower b in its operative position in the passage a, and a lever, L, or other suitable means being employed for raising the follower to push the completed slug out of the aforesaid passage, as hereinafter explained.

Vith the upper portion of the channel a are used different plungers and other implements-wiz, first, a plunger, c, formed at its lower end with a circumferentially-reduced portion, d, in the form of a truncated cone, as shown at 1 in Fig. l of the drawings; second, an annular cuttingdie, e, in the form of a wad-cutter, arranged on top of the table A, and with its eye in coincidence with the channel a, the cutting-edge of said die projecting upward, and above it is arranged a punch, f,

which, by its striking the cutting-edge of the die, cuts a circular disk out of any substance interposed between said die and punch; third, a plunger, g, sliding longitudinally in a vertical channel through the center of the aforesaid punch; and, fourth, a plunger, h, having its lower end formed with a plain horizontal face and. tted closely to the interior of the passage a.

In carrying out the invention we proceed as follows: We drop into the passage a a lead blank, a, as shown at o in Fig. l of the drawings, which blank may be either in the form of a round shot or a cylindrical piece of lead. Ve then enter the plunger c and press the same down onto the lead blank with sufficient force to cause the blank a to lill the conical depression in the end of the follower b, and at the same time receive in its back an indentation or central recess, r, from the impingement of the conoidal end d of the plunger, thus forming arearward-proj ectin g peripheral rim, s, on the back of the slug, for the purpose hereinafter presently explained. The plunger c is then removed from the passage a, and the die e adjusted over the mouth of the passage. Then felt z' is placed over the die and the punch f brought down to cut out of the felt the circular disk Z, which is immediately pushed down into the passage a by the plunger g, which moves in the axis of the punch. The die e, together with the punch f and plunger g, is then removed, and the plunger his introduced in the channelY a and drivenl or forced down. In so doing the felt disk is pressed into the recess o' of the slug, and the rim s on the back of the slug becomes upset and turned inward and clinched around the felt disk, as illustrated at 3 in Fig. -1, thus securely fastening the felt disk to the lead slug. Vhen this is completed, the plunger his withdrawn from the channel a, and the follower b forced upward to push the completed felted slug out of the channel. j

Having described our improvements, what We claim is- 1. The improved process of manufacturing felted slugs, consisting in forming the back of the lead slug with a rearward-projecting peripheral rim, and then pressing onto the same the felt disk and simultaneously clinching' the rim of the slug inward around the felt disk to fasten the same, substantially as set forth.

2. The improved process of manufacturing felted slugs, consisting in, iirst, forming the lead slug by pressing a lead blank into a mold or die and simultaneously pressing into the back of the slug a central recess, and then, while holding the lead slug in its said mold7 pressing a felt disk onto the back of the slug, and simultaneously clinching inward and around the felt disk the edge of the recess in the slug7 substantially as specified and shown. In testimony whereof we have hereunto signed our names and afxed our seals, in the presence of two attesting witnesses, at Herkimer, in the county of Herkimer, in the State of New York, this 18th day of September'1883.
